Hi Shaun You're not the first person to be looking for exact matches in a field taking priority over other fields, but I'm not sure if this is possible in Sphinx. It's probably worth asking about this on the Sphinx forum instead, because it's definitely beyond my knowledge, and it's not tied to Ruby/Thinking Sphinx. http://www.sphinxsearch.com/forum/
Sorry I can't be more help at the moment. -- Pat On 13/01/2010, at 1:24 PM, Shaun wrote: > Hi > > I have indexed two fields from my database, a title and author.
